Recreating a real life object in 3Ds Max. (and breaking it)

Sorry if the title isn't descriptive enough, but I'm sure what the process of doing this is called.

Basically I would like to recreate a wall from inside my footage in 3Ds Max but without changing its looks. Then I want my actor to be able to come in and break the wall. This is really hard to explain, but I do have a video of the type of thing I'm trying to achieve.

From 0-10 Seconds:






I would assume I would have to use some 3d motion tracking, and rotoscope out the person in the shot. But as for matching the wall perfectly to my scene is what I would really like to know how to do.

Thanks in advance!

Hi Jon -

It's the 3D motion tracking (camera tracking) which allows you to match in the wall via camera matching (and either rotoscoping or chroma keying). You'll find a complete education right here at The Foundy's website:

I've been looking at camera tracking software for a while, and this seems to be the most bang for the buck. Many of the others are upwards of a thousand dollars. Camera Tracker for AE is 280 dollars, or you can rent it per project for a minimum 70 dollar (US) rental, which would give you a month to learn and apply it. Pretty good deal.

The process isnt simple but i have achieved this effect before.

I think I matchmoved a 100x100x5 box to the position of the wall, fractured it with the rayfire plugin, added a Matte/Shadow material on fractures that dont fall in the simulation, added a color to the other fractures that is similar to the color of the wall (in the example = grey) and left a brick texture behind the fractures. its really hard to explain. sorry if thats unclear. the matte/shadow material for the fractures that dont move is the key to the effect though.
